Abstract
The utility model discloses an inflatable oil well plugging device and belongs to the technical field of oil exploitation. The inflatable oil well plugging device mainly solves the problem of oil well plugging in existing oil exploitation processes and structurally comprises an air compression pump, a cable, airbags, an air guide pipe and a gravity bob. The output end of the air compression pump is connected with the head end of the air guide pipe, the tail end of the air guide pipe is connected with the gravity bob, the middle of the air guide pipe is uniformly provided with airbags, and the cable is connected with the air compression pump; the bottom of the air compression pump is provided with four wheels; five airbags are uniformly distributed on the air guide pipe in the direction of the air guide pipe. The diameter of inflated airbags is larger than that of an oil well, and the airbags are made of rubber; the air guide pipe and the airbags are glued through waterproof glue; the gravity bob is solid, is made of iron and is in a conical shape, and the tail end of the gravity bob is connected to the tail end of the air guide pipe. The inflatable oil well plugging device plugs the oil well through resistance of the airbags, and due to the fact that the airbags are distributed in a string structure and accordingly can dissipate pressure, can improve the plugging effects.
Description
Technical field
The utility model relates to a kind of air filling type oil well plugging device, belongs to oil exploitation mechanical field.
Background technology
Oil well is the eyelet being drilled to by boring method.General oil well reaches after oil reservoir at brill, be lowered to production string, and the annular space between sleeve pipe and the borehole wall injects oil well cement, to safeguard the borehole wall and sealing oil, gas, water layer, by the requirement of oil field development, with perforating gun, penetrate out oil reservoir afterwards, form passage, be lowered to oil pipe, by the suitable stream method that lures, oil is risen to well head by oil well shaft bottom.In recovery process, because the factors such as pressure sometimes can be freeed the security incidents such as blowout, now with regard to needs, fast oil well is carried out to shutoff.
Utility model content
The utility model, for the problem of the shutoff of oil well in current oil exploitation process, has designed a kind of air filling type oil well plugging device.
The technical scheme in the invention for solving the technical problem is:
This kind of air filling type oil well plugging apparatus structure comprises: air pressure pump, cable, air bag, wireway, gravity drop hammer; Air compressing pump output terminal connects wireway upper end, and wireway lower end connects gravity drop hammer, and air bag is bonded on wireway by marine glue, and air bag diameter under inflated condition is greater than drilling well-head internal diameter, and wireway lower end connects gravity drop hammer.
Described air pressure pump bottom is provided with four wheels.
Described air bag is evenly arranged in along in the drilling well of wireway direction, and air bag is bonded on wireway by marine glue respectively, and along five air bags of wireway direction distribution, during inflated condition, air bag diameter is greater than drilling well diameter.
Between described wireway and air bag, pass through marine glue bonding connection.
The utility model has the following advantages:
1. the utility model is novel unique, in use procedure, by air pressure pump, gas is pressed in air bag, by the resistance oil well of air bag, carries out shutoff, because air bag is string data structure distribution, pressure is disperseed, and has improved plugging effect.
2. material is cheap, and cost of manufacture is low, and application is wide.
Accompanying drawing explanation
Structural representation when Fig. 1 is the utility model shutoff;
Structural representation when Fig. 2 is the utility model unaerated;
In figure: 1 is that air pressure pump, 2 is that cable, 3 is that air bag, 4 is that geological stratification, 5 is that wireway, 6 is gravity drop hammer.
The specific embodiment
As shown in Figure 1, 2: a kind of air filling type oil well plugging device, its structure comprises: air pressure pump 1, cable 2, air bag 3, wireway 5, gravity drop hammer 6; Air pressure pump 1 output connects wireway 5 upper ends, and wireway 5 lower ends connect gravity drop hammer 6, and air bag 3 is bonded on wireway 5 by marine glue, and air bag 3 diameter under inflated condition is greater than drilling well-head internal diameter, and wireway 5 lower ends connect gravity drop hammer 6; Air pressure pump 1 bottom is provided with four wheels; Air bag 3 is evenly arranged in along in the drilling well of wireway 5 directions, and air bag 3 is bonded on wireway 5 by marine glue respectively, and along five air bags 3 of wireway 5 directions distributions, during air bag 3 inflated condition, air bag 3 diameters are greater than drilling well diameter; Between wireway 5 and air bag 3, pass through marine glue bonding connection.
During use, wireway 5 is stretched in to oil well inside, gravity by the gravity drop hammer 6 of wireway 5 terminals is sent wireway 5 into oil well inside, now starting air pressure pump 1 is filled with gas in air bag 3 and makes it to expand, because diameter after air bag 3 inflations is greater than oil well diameter, therefore the air bag 3 by string data carries out shutoff by oil well.
The above, be only the specific embodiment of the present utility model, and in the scope that those of ordinary skill in the art disclose at the utility model, the variation that can expect easily, within all should being encompassed in the protection domain of utility model.
